Application April 16,1948, Serial No. 21,432 1 Claim. (01. 131--180) This invention relatesto improvements in double bowl tobacco smoking pipes, and the primaryobject of the invention is to provide an efiicient and cool smoking pipeof this type which is of simplified and more practical construction,wherein the tobacco present in one bowl acts as a filter for the smokeand moisture involved in the smoking of the other bowl, and in which thestem is arranged to be selectively inserted in the top of the bowl beingused at the time as the filter chamber, in such a way that the filteredsmoke is drawn through the stem from the upper part of such chamberrather than from the bottom therein wherein accumulation of noxiousmoisture otherwise naturally occurs, so that the stem remainscomparatively free of noxious moisture.

Other important objects and advantageous features of the invention willbe apparent from the following detailed description and accompanyingdrawings, wherein, for purposes of illustration only, a specificembodiment of the invention is set forth.

In the drawings:

Figure 1 is a vertical longitudinal section taken through saidembodiment.

Figure 2 is a top plan View thereof, and

Figure 3 is a side elevation of the stem per se.

Referring in detail to the drawing, the numeral 5 generally designatesthe body of the illustrated smoking pipe, said body being longitudinallyelongated, with semi-cylindrical ends 6, 6; parallel plane sides 1, l, afiat bottom 8, and a fiat top 9. The body 5 is formed with twolongitudinally spaced similar bowls 19, I having fiat coplanar bottoms I0', It in spaced relation to the body bottom 8, and having slightlyflared upper ends it openin through the top 9. Sole communicationbetween the bowls l0, H] is provided by a relatively small diametersmoke passage l2 formed horizontally through the Wall I3 separating thebowls and located above the lower ends of the bowls so as to leave belowthe passage suificient space to accommodate any expected accumulation ofnoxious moisture without permitting such to flow between the bowls or tobe circulated between the bowls by ordinary smoking suction.

The stem generally designated [4 comprises a generally cylindrical bodyhaving a slightly tapered lower end portion 16 adapted to seat in theflared openings II, II of the bowls l9, H). The body [5 has a radialtapered projection I! on one side constituting the pipe bit and formedaxially with a bore I8 terminating at its inner end in a crossedjunction 19 with the upper end of the axial smoke passage 20 openingthrough the lower end of the body 15.

When the body I 5 is inserted in one of the bowls I0 the tobacco in theother bowl is ignited and smoke therefrom is drawn through the passageI2 into the said one bowl l0 and upwardly through the tobacco therein,then acting as a filter and moisture trap, and then through the stempassage 2!] to the bit passage l8. After the tobacco in the first bowlhas been consumed, the first bowl may be refilled with tobacco and thebody l5 transferred thereto and the tobacco subsisting in the other bowlmay be replaced or consumed as is, the tobacco in the first bowlthereupon acting as a filter and moisture trap.

Iclaim:

A smoking pipe comprising a body including a fiat bottom, parallelspaced upstanding plane sides, and upstanding semi-cylindrical endsfacing each other and connecting the plane sides together, a verticallydisposed wall fixedly positioned within said body and extendingtransversely between said plane sides substantially centrally of thelatter and subdividing said body into two tobacco containing bowls eachwith an open top, the open top of each bowl being flared, said wallbeing provided with a smoke passage extending horizontally therethroughadjacent to and spaced above said bottom and having one end incommunication with one of said bowls and having the other end incommunication with the other of said bowls, and a stem comprising a bodyhaving a tapered lower end portion arranged for vertical insertion inthe open top of one of said bowls, a bit projecting horizontally fromsaid stem, and passage means extending through said bit and said bodyand opening above the tobacco in said one bowl whereby smoking suctionapplied to said bit will draw smoke from ignited tobacco in said otherbowl through said first mentioned passage in said wall into said onebowl and upwardly through the tobacco in said one bowl to said passagemeans in said bit, the open ends of said bowls being of the same flaringwhereby said stem body may be inserted in either bowl.
